COMBINED WATER S TILL AND HEATER.

SPECIFICATION forming part of Letters Patent Ala 648,337, dated April24, 1900.

Application filed Ma'y22,1899. Serial No. 717,791. (No modem purposes asnow sold in the market are waste-- ful of fuel. Moreover, they aretroublesome in use, because in order to supply the condenserwith watersufficiently cool to effectually condense all the steam generated itmust be frequently emptied and replenished from a pail or pitcher.Further, these stills require unremitting attention to prevent them fromboiling dry and a consequent burning ormelting down of the apparatus.

The prime object of my invention, therefore, is to provide an improvedapparatus for distilling water for domestic uses that may be connectedwith the ordinary stand-boiler,-

so that water for bathing or kitchen purposes may be heated during thedistilling process and in which water in the stand-boiler may be heatedindependently of any operation of the still.

A second object of my invention is to provide means for aerating to someextent the distilled water. a

A third object of my invention is to provide means for automaticallyregulating the supply to the boiler and generator. 7

My invention consists in. the construction hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a side view of a stove-rangeand stand-boiler, showing my distilling apparatus combined therewith.Fig. 2 is a front view of the same. Fig. 3 is a longitudinal sectionalview of the condenser. Fig. 4 is a transverse sectional View of thecondenser onthe line 0c 00, Fig. 3. Fig. 5 is a central sectional viewof the generator, illustrating incidentally the low-water alarm. Fig. 6is a detail illustrating the device for regulating the supply of waterto the generator.

In the drawings like characters of reference designate correspondingparts.

1 designatesthe ordinary stove=1'ange,which is furnished in its fire-boxwith an ordinary water-back. (Not shown, but well understood.) The fuelfor this range is gas, natural or artificial, and independent burnersare furnished for the openings at the top, the baking-oven, and thewater-back,'so that the burner for the water-back need not be lightedwhen the still is to be operated, and if it is desired to heat water inthe stand-boiler without operating the still the burner for thewater-back is to be lighted.

2 designates the ordinary stand-boiler, that is connected with the waterback of the range by pipes 2 2, as usual, and is provided with pipesconnecting it with the street-main and with discharge pipes and cooks,(not shown, but well understood,) so that the flow through the boilermay be established.

3 designates the condenser, that is conveniently'cylindrical in formandprovided with heads 3 and 3 screwed into the opposite ends of thecylinder. Within the cylinder is a cone-shaped chamber 4, having a pipe4 connected with its large end passing through the head 3, said pipeleading to the retort, and a pipe 4 connected to its small end that ispreferably bent around back toward the large end and passed through thehead 3, the protruding part of said pipe being provided with a cock, asshown. From the lower portion of, the large end of the cone-shapedchamber there extends a pipe 4, also passing through the head 3*, thatconveys the water distilled in the chamber 4 to a suitable receptacle 5.Soldered or otherwise secured to the smaller end of the cone is aspider-frame 4 the arms of which extend to and touch the inner sides ofthe cylinder and afford a brace or support for the small end of thecone, it being observed that the larger end is sufficiently supported bythe pipes connecting it and the head 3. From this construction it willbe observed that the head 3 with the cone and parts connecting the same,may be bodily removed and all the parts cleansed at any time necessary.The condenser is connected with the pipes 2 2* by pipes 2 2 preferablypassing through the head 3 It will be observed that the condensing-coneis entirely surrounded by water when the'cyl inder is filled.

The generator 6 consists of a vessel its body portion shaped somewhatlike an or dinary kettle, but having a steam-dome 6 screw-threaded inthe top thereof and having means for detachably coupling therewith thepipe 4:. Attached to-the top of this dome 6 is a tube 7, Fig. 5, at theupper end of which n is awhis tle 7, so that when the water hecomes lowin thegenerator the escaping steam will sound an alarm; but I haveprovided a device thatwill render the use of an alarm unnecessary,Itconsists of an automatic supply for the generator and means forautomatically'regulating that supply Extendin 'tpreferably from theupper portionof the I head 3 (because the water there after a short timewill be more or less warmed) is a' pipe 8, that is coupled to a cock 8*,supported at l the side of't'he generator over the upper end of a pocketor well 6*, that communicates at its lower end with the interior of thegenerator 6, The valve of the cock has fixed to-it an arm 8*, slottedatits free end, to which is connected the upper end of a rod 9', thatworks I vertically in aperfora-ted bushing -6 at the top of thegenerator, and on the lower end of this rod is screwed afloat .9, thatrises and falls with the rise and fall of the level'of the water in thegenerator. The rising and falling of the float closes and opens,respectively,

the cock, andso automatically regulates the supply of water, thusrendering the operation of the apparatus perpetual, except for naturalFrom the foregoing it will be observed that the condenser becomes apermanent part of the apparatus ofthe kitchen and that in order toobtain distilled water it is only necessary to .place the generator onthe stove and make the proper connections with the con The devices forautomatically r'egu- I 'lating the supply-can be dispensed with, as

may also the alarm. If theautomatic supply is used, the alarm willseldom operate,

and then only through some choking of the supply-pipe or failureof thefloat to operate.

The function of the pipe 4 Fig. 3, is to serve first as a vent to allowthe escape of 3 such volatile gases as may arise in the initial heatingand boiling of the water in the generator, and after this has takenplace the pipe may be closed but another important function of this'pipeis to admit air to aerate the condensing steam and resultant water, re-

p the ordinary stand-boiler shall contain a relhavingativelylarge-quantity of-cold water. Ordinarily, however, abundant supply ofdistilled water for adays use will be obtained before or by'the time allthe water in the standboiler has been heated by the operation of thestill. r

' if the .hot water required in the family hap pens to exceed thatobtained by operating the still for the ordinary supply of distilledwater, the surplus hotwater may besecured by removing the generator fromthe stove and heating the water-back or the hot-water tank orstand-boiler in the ordinary way.

Aside from theextreme convenience of my apparatus, its economy will beappreciated when the quantityof fuel required to heat the water in theordinary stand-boiler is calculated. v V I What Iclaim,anddesire tosecure by Letters Patent, is

' 1. In combinatio n with a closed tank having inlet and outlet pipes,the'outlet-pipe hav- 1 ing astop-cock, said tank being adapted tocontain water under pressure, a separate chamber connected by pipes andcommunt ca ting with said tank, said separate chamber containing acondenser for condensing or distilling water whereby the water in saidtank Q may be heated by the distilling process in said I separatechamber and stored for use in said tank substantially as described.

2. In combination with a 'stove having a water-back, a closed tank forcontaining wa- 1 ter under pressure communicating with said 1 waterbackand also having water-supply and outlet pipes, the outlet-pipe having astop- E cock, a sep'arate'chamber connected by pipes and-communicatingwith said tank, said separate chamber containing a condenser forcondensing or distilling water whereby the water in said tank may beheated andstored in i said tank either fromthe water-back or from thecondenser, substantially as described' 3. In a distilling apparatus aclosed tank having inlet and outlet pipes, the outlet-pipe having astop-cock, said tank being adapted to contain water. under pressure, aseparate chamber containing'a condenser for condensing or distillingwater whereby the water in said tank may be heated by the distillingprocess in said separate chamber and stored foruse in said tank combinedwith a retort or boiler having a supply-pipe from said separate chamber,a valve in said supply-pipe, a float in said retort or boiler connectedwith said valve so as to operate the same upon its rise or fall todiminish or increase the flow from said pipe, substantially asdescribed.

, 4:. In a distilling apparatus a closed tank having inlet and outletpipes, the outlet-pipe having-a stop-cock, said tank being adapted tocontain water under pressure, a separate cold-water chamber containing acondenser for condensing or distilling water whereby the water in saidtank may be heated by the distilling process in said separate chamberand stored ,for use in said tank, said convoir to contain water underpressure, a pipe connecting the lower part of the reservoir with thecondenser and a pipe connecting the condenser with the reservoir abovethe junction of the first-mentioned pipe whereby circulation of waterfrom the reservoir to the condenser and back to the reservoir isobtained, substantially as described.

In testimony whereof'I aflix my signature in presence of two witnesses.
